This review examines the functions of vitamin D and its receptor in skin and explores how these are regulated, reporting no new clinical results.

This review discusses the immune roles of keratinocytes in wound healing and chronic wound inflammation, emphasizing their potential impact on chronic wound pathology and highlighting areas for future research.

This review discusses the roles of TGF-β family signaling in regulating normal and cancer stem cells and highlights the need for further research to develop potential cancer treatments; it reports no new results.

In this study, mycorrhizal fungal inoculation was associated with increased root-hair growth and enhanced drought tolerance in trifoliate orange by modulating auxin synthesis and transport under water stress conditions.

This review discusses the historical development, mechanisms of action, and potential new clinical applications of the drug cepharanthine, highlighting its multi-faceted pharmacological properties; it reports no new clinical results.

This study found that C8/144B antibody exclusively binds to the hair follicle bulge and not the epidermal stratum basale, with cytokeratin 19 serving as a key marker of certain basal keratinocytes that decrease with age.

This review examines the impact of vitamin D signaling in extraskeletal tissues and notes that expected benefits from animal and cell studies have not been consistently replicated in human clinical trials.

This paper discusses X-linked ichthyosis and its genetic causes, focusing on biochemical pathways and their role in epidermal differentiation and barrier function, but it presents no new clinical findings.

In this study, researchers found that TCDD exposure accelerated differentiation and altered gene expression in human epidermal cells, indicating the epidermal barrier as a target of TCDD-activated AHR.

This review outlines a diagnostic framework for clinicians to distinguish different types of inherited ichthyoses and suggests further testing and treatment strategies, but reports no new clinical results.

This study suggests that the GPX-PDE1 and GPX-PDE2 genes in white lupin enhance root hair development and contribute to Pi limitation acclimation by facilitating glycerophosphodiester degradation.

This review discusses the properties and therapeutic potentials of beta-sitosterol, highlighting a need for more detailed studies on its mechanisms and long-term effects in humans; it reports no new results.

This study found that human hair follicles express erythropoietin and its receptor, suggesting these follicles may use erythropoietin signaling to modulate apoptosis under stress conditions like hypoxia and chemotherapy.

This review discusses the antiviral potential of cepharanthine against SARS-CoV-2, noting its effectiveness in preclinical models but presenting no new clinical results.

This review discusses the senescence–stemness connection in cellular biology and reports no new findings, highlighting implications for both tissue repair and aggressive cancer behavior.

This review discusses the role of the hedgehog signaling pathway in hematological cancers and its potential as a therapeutic target; it reports no new clinical findings.

These guidelines review the management of complications and specific forms of congenital ichthyosis and report no new results; they summarize expert and evidence-based recommendations for clinicians.

This review discusses the potential role of Wnt signaling in aging-related heart diseases and reports no clinical results.

This study found that activating Nrf2 in human hair follicles significantly reduced oxidative stress, lipid peroxidation, and protected against hair growth inhibition, suggesting a protective role for Nrf2 against redox insult in this context.

This guide reviews the biology of sebaceous glands and their evaluation methods, emphasizing their roles beyond lipid production in skin health and disease, and reports no new research results.

This review examines the main absorption sites and influencing factors for orally administered drugs, highlighting variables such as solubility and gastrointestinal conditions that affect drug absorption in the small intestine and the development of effective drug delivery systems.

Research on epidermal stem cells has advanced significantly, showing promise for improved clinical therapies.

This review discusses the presence of the StAR protein in 17 non-classical steroidogenic tissues, suggesting that advanced detection methods are needed for a complete understanding of its functions in these tissues.

This study found that androgen receptor activation in adult mouse skin reduces β-catenin-induced hair follicle growth and sebaceous gland conversion, highlighting its role in stem cell fate decisions.

This review suggests that brassinosteroids may have similar biological activities in both plants and other organisms, prompting further exploration of steroid regulation mechanisms across different life forms.

This review discusses the embryonic origins and characteristics of various stem cell populations in the skin, but it provides no new experimental results.

This review explores the role of Eph receptors and ephrins in skin cell processes, discussing their potential for therapeutic targeting in dermatological disorders, but it presents no new research findings.

The authors describe drug repurposing as a promising strategy for finding new uses for existing drugs, noting it is efficient, cost-effective, and poses lower risks than traditional drug discovery processes, potentially aiding in the treatment of rare and difficult-to-treat diseases.

This review highlights that children with adrenal disorders may experience neurological and psychiatric symptoms, with potential long-term cognitive and behavioral effects from excess glucocorticoids.
